Vox only, interesting. Been enjoying some Comix2go titles on the Playbook.

I've been using ComiXology because they have a store with a lot of major publishers involved (I want to buy comics, not torrent them). Most comics for Kobo appear to be Vox only, which I do wonder about because the Kobo app is available for a lot of devices that are perfectly capable of displaying them. *shrug*
